Cyclocross Magazine was the first to see Clement’s X’Plor USH mixed-terrain (gravel) tire way back in August 2011, but the tires, along with the sister X’Plor MSO tire, now have become some of the more popular gravel grinder tires, with smooth-rolling, long-lasting treads and three different widths to chose from. We’ve been testing these tires recently, and will have a review coming soon, but we took a closer look at the tires at Frostbike 2014.

Walk around Frostbike and you can’t help but notice two things: 1) the number of bikes being shown or equipped with Clement tires; and 2) the number of companies talking about gravel.

Clement seems to have become the default tire option for gravel bikes, and for good reason due to the six different variations of two gravel-oriented treads.

The X’Plor USH tire (left) comes in a 700x35c width, and has 60tpi and 120tpi versions, and Clement says it is aimed at riders who look to tackle “dirt roads, touring, and urban assault.”

The X’Plor MSO tire (two right) comes in both 700x32c and 700x40c widths in 60tpi and 120tpi casings, and is targeted to “bridge the gap between pavement and blazing your own trail.” The MSO tire is named for the airport code of Missoula, Montana, home of the Adventure Cycling Association. Got an cycling adventure planned? Clement wants you to roll with them.
